Detailed Description
The invention is explained in more detail below:
the visual fatigue-preventing system consists of three parts, including screen display, pupil state detecting device, microprocessor, etc. The pupil of the human eye is enlarged in dark environment, and is reduced under the irradiation of strong light. The pupil dilation and dilation varies with the intensity of the ambient light, and when the display is just lit, the brightness may be a bit darker or a bit brighter than optimal for the human eye. At this time, the pupil state detection device on the display monitors the enlarging state of the human pupil, and the detection device transmits the detected data to the microprocessor. The microprocessor is connected with the brightness adjusting PIN of the display, compares the received data with a set normal state value, and when finding that the pupils of human eyes are in an enlarged state, the microprocessor sends an instruction to the brightness adjusting PIN of the display to instruct the display to adjust the brightness value to the corresponding brightness when the pupils are in the normal value and keep the brightness; when the pupils of the human eyes are in a shrinking state, the microprocessor sends an instruction to the brightness adjusting PIN of the display to instruct the display to dim the brightness value to the corresponding brightness when the pupils are in a normal value and keep the brightness.
The implementation method comprises the following steps:
the display brightness is too dark and is adjusted to be bright:
firstly, the method comprises the following steps: when the eye brightness adjusting device is used for the first time, a pupil state corresponding to the optimum eye light intensity of a user is defaulted in the microprocessor, so that the pupil state of the user detected later is compared with the pupil state to determine how to adjust the brightness of the display.
Secondly, when a user opens the electronic product to use the screen display device, the pupil state detection device arranged on the display monitors the enlarging state of the human pupil.
Thirdly, the method comprises the following steps: the detection equipment transmits the currently detected pupil state data to the microprocessor, and the microprocessor compares the received pupil state data with a default normal state value to judge the state of the current human eye pupils.
Fourthly, when the microprocessor compares the data and finds that the current pupil is in the enlarged state, the brightness of the display is judged to be slightly dark, and the brightness of the display needs to be adjusted to be bright. The microprocessor will then continuously instruct the brightness adjustment PIN of the display to instruct the display to increase the brightness. Since the pupil of the human eye is gradually reduced while the brightness of the display is increased, the pupil state detection device can send the pupil state detected at present to the microprocessor so that the microprocessor can compare the pupil state with the default normal state value. When the microprocessor finds that the pupil has shrunk to be the same as the default value, it no longer gives an instruction to turn on the display to the brightness adjustment PIN of the display, at which time the display stays and is kept at the brightness most comfortable for the human eye.
And (3) over-brightness and dimming of the display:
firstly, when a user opens the electronic product to use the screen display device, the pupil state detection device arranged on the display monitors the amplification state of the human pupil.
Secondly, the method comprises the following steps: the detection equipment transmits the currently detected pupil state data to the microprocessor, and the microprocessor compares the received pupil state data with a default normal state value to judge the current state of the pupils of human eyes.
Thirdly, when the microprocessor compares the data and finds that the current pupil is in a shrinking state, the brightness of the display is judged to be slightly bright, and the brightness of the display needs to be dimmed. The microprocessor will then continue to instruct the display to dim the brightness by issuing commands to the brightness adjustment PIN of the display. The pupil of the human eye is slowly enlarged while the brightness of the display is reduced, so that the pupil state detection device can send the pupil state detected at present to the microprocessor so as to compare the pupil state with the default normal state value. When the microprocessor detects that the pupil has dilated to the same extent as the default value, it no longer instructs the brightness adjustment PIN of the display to dim the display, and the display stays and remains at the most comfortable brightness for the human eye.
Through the intelligent adjustment of the brightness of the display, the display can stay at the most comfortable brightness of human eyes at any time, so that the aim of relieving visual fatigue and protecting eyes is fulfilled.
